PhidgetBridge 4-Input
Note: The 1046_0B is identical to the 1046_0, except that it comes pre-assembled in a plastic shell enclosure and you have the option of which length of USB cable you want to include.
The PhidgetBridge lets you connect up to 4 un-amplified Wheatstone bridges, such as:
-
- Strain gauges
-
- Compression load cells
-
- Pressure sensors/Barometers
-
- Piezoresistive accelerometers
-
- Magnetoresistive sensors (Compasses)
The data rate and gain values can be configured in software.
